Reverse Mechanism of Gravitational Time Dilation and Decisive Verification Using GPS

Whether the atomic transition spacing varies with gravitational potential is anuntested presupposition in general relativity. This assumption directly deter-mines the causal direction of gravitational time dilation: if the atomic transitionspacing is a universal constant, time fl...

Improving defect detection of nuclear welds using adaptive imaging based on uncertain material parameters optimization

Weld inspection in the nuclear sector is crucial for ensuring the structural integrity and safety of reactor cooling piping systems. Given the strict safety requirements, reliable and accurate Non-Destructive Evaluation (NDE) techniques are essential for the early detection and c...

Stronger Vegetation Cooling in a Warming City: A Google Earth Engine Analysis of NDVI–Land Surface Temperature Relations in Rajshahi, Bangladesh (2001–2025)

Rapid urbanisation in mid-sized South Asian cities has intensified the surface urban heat island, yet satellite assessments of the vegetation–temperature relationship for Rajshahi, Bangladesh, remain scarce. This study quantifies it across 546 km² of Rajshahi City for four pre-mo...

First-principles identification of optically efficient erbium centers in GaAs

Gallium arsenide (GaAs) doped with erbium (Er), a material of interest for optoelectronics and quantum information, has been studied for decades. Yet the formation of Er luminescence centers in the semiconductor host and their properties are still not well understood. Here we pre...

Exact Results on the Flat Three-Torus: Stable Winding States, Cascade Termination, Harmonic Flow, and Arithmetic Spectral Gaps — with an Information-Processing Analogy

This record presents exact results about a stipulated quadratic split model on the winding lattice of the flat three-torus T³ = R³/LZ³, together with a separate, explicitly model-dependent information-processing analogy. The exact results and the analogy are kept distinct: the ge...

Hybrid renewable energies for rural/urban electrification in emerging economies: A bibliometric review

Limited economic viability, energy scarcity, rising power costs, geographical limits, and infrastructural issues are the main challenges of regional electrical network growth. Though intermittent, renewable energy is clean, sustainable, and infinite. Off-grid or grid-connected hy...

The Unfinished Revolution of Garden Cognition in China

This article serves as a presentation to my new book, 'Zhuozheng Yuan Kaolun' ('An Evidential Inquiry and Analytical Treatise on the Garden of the Inept Administrator'), written at the request of the 'Xinshu Ji' (New Book Season) WeChat official account. The original text is publ...

Silentium: A Delayed-Memory Interacting Dark Energy Model with Asymptotic ΛCDM Attractor

We present a phenomenological cosmological framework in which cosmic acceleration emerges from a delayed radiative coupling between the radiation field and a cosmological energy continuum. The model introduces a single memory timescale, τSCF, and a coupling constant, κSCF, genera...

The Mean Totient Entropy: A New Number-Theoretic Constant and its Dirichlet-Type Representation over the Primes

The Mean Totient Entropy: A New Number-Theoretic Constant and its Dirichlet-Type Representation over the Primes For a positive integer n, the divisors carry a canonical probability vector (φ(d)/n) over d | n (Gauss: Σ_{d|n} φ(d) = n). Its Shannon entropy H(n) = −Σ_{d|n} (φ(d)/n)·...

Regional Communication Officer, UNAIDS Latin America (2011): Documentary Evidence of Professional Contributions

This revised archival deposit documents the professional communications work undertaken by Verónica Pereyra Carrillo as Regional Communication Officer at the UNAIDS Regional Support Team for Latin America, based in Panama, from February to December 2011. Her responsibilities incl...

A separable and asymptotic-preserving dynamical low-rank method for the Vlasov–Poisson–Fokker–Planck system

We present a dynamical low-rank (DLR) method for the Vlasov–Poisson–Fokker–Planck (VPFP) system. Our main contributions are twofold: (i) a conservative spatial discretization of the Fokker–Planck operator that factors into velocity-only and space-only components, enabling efficie...

Numerical stability revisited: A family of Benchmark problems for the analysis of explicit stochastic differential equation integrators

We revisit the numerical stability of four well-established explicit stochastic integration schemes through a new generic benchmark stochastic differential equation (SDE) designed to assess asymptotic statistical accuracy and stability properties. This one-parameter benchmark equ...

Deterministic Language Architecture: A Formal Category Definition and Architectural Specification for Non-Probabilistic Language Generation Systems

Canon³ — The Lume Synthetic Organism Canon (L-SOC) Language Architecture Volume I. This paper formally defines Deterministic Language Architecture (DLA) — a new category of language generation system in which output is governed by deterministic architecture rather than probabilis...

Local Discontinuous Galerkin method for the prescribed mean curvature equation

We construct a non-polynomial local discontinuous Galerkin (LDG) scheme for the prescribed mean curvature equation to approximate boundary gradient blow-up solutions and obtain error estimates.
